Measuring Judicial Biases with Artificial Intelligence: Evidence from Chinese IP Litigations

How does judicial fairness in intellectual property (IP) litigations shape the incentives to innovate? This talk examines local bias in IP litigation and its consequences for firm-level innovation in China.

Using a dataset from China Judgements Online on Chinese IP court decisions from 2014–2020, a striking puzzle emerges: despite widespread concerns about local protectionism, non-local plaintiffs frequently win at higher rates than local ones. Two competing forces explain this — a "local protectionism effect," whereby local fiscal incentives bias courts toward local firms, and a "picket fence effect," whereby litigants anticipate bias and self-select out of bringing cases, quietly distorting the pool of disputes that reach the courtroom.

To cut through this identification challenge, researchers train an LLM–based "AI court'' on cases in which both plaintiff and defendant are non-local for which the incentives of local courts to bias either side are absent, generating counterfactual fair win-rates for all other disputes. Comparing observed and predicted win-rates reveals significant judicial bias. A 2019 reform centralizing appellate jurisdiction over a subset of IP cases, namely the technical cases, directly to the National Supreme Court shows that stronger central supervision substantially improves judicial accuracy and curtails bias — and measurably increases firm innovation.

The findings underscore that impartial courts are not just a procedural ideal, but a concrete driver of economic dynamism.
